Steel beams do not need to be fireproofed, but they may be coated with a fire-resistant material. Steel beams are often coated with a fire-resistant material because steel is a combustible material. When steel beams are exposed to a flame, the heat from the flame can cause the steel beam to ignite and the beam can then burn quickly. The coating on the steel beam will help to prevent the metal from igniting and from burning quickly.

Steel beams do not need to be fireproofed, but they should be treated with a fire-resistant coating. This will help to protect the steel from heat and flames in the event of a fire. A properly-coated steel beam can withstand temperatures up to 1,700 degrees Fahrenheit without sustaining damage. However, if the beam is not coated or if the coating is damaged, it can quickly melt under high heat and may fail structurally.
